Question
 Which of the following best describes validation
testing?Solution
Ensuring the software meets user requirements and intended use.
2387.56 + ? – 2248.14 = 1765.45 – 1574.23
 15.78% of (287 + 302) + 12³ = ?% of 170 + 8 × 14 + 3²Â
? = (5.8)2 + (8.9)2 + (4.7) 2 + 24.7% of 20
49.99% of 639.99 + 159.98% of 49.99 = ?2
(14.66)2 + (343.84 ÷ 3.88 - 55.87) = ? + 91.23
(18.21)² - (12.9)² = 20% of 649.9 - ? + 400.033
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
49.96% of 120.21 + √(15) ÷ 1.87 × 4.41 = ?Â
(3/8) × 479.84 + (2/5) × 449.67 = ? × 12.25Â
64.889% of 399.879 + √? = 54.90% of 799.80 – 44.03% of 400.21
